Properties

Property	Type	Access	Description
blackColorThreshold	number (range: 0 - 100)	r/w	The minimum amount (as a percentage) of black ink required before the black width setting is applied. (Range: 0 to 100)
blackDensity	number (range: 0 - 10)	r/w	The neutral density value at or above which an ink is considered black. (Range: .001 to 10)
blackWidth	Measurement Unit (Number or String) (range: 0 - 8)	r/w	The black width. (Range depends on unit. For points: 0.0 to 8.0; picas: 0p0 to 0p8; inches: 0 to 0.1111; mm: 0 to 2.822; cm: 0 to .2822; ciceros: 0c0 to 0c7.507)
colorReduction	number (range: 0 - 100)	r/w	The degree (as a percentage) to which components from abutting colors are used to reduce the trap color. (Range: 0 to 100) Note: 0% makes a trap whose neutral density is equal to the neutral density of the darker color.
defaultTrapWidth	Measurement Unit (Number or String) (range: 0 - 8)	r/w	The default width for trapping all colors except those involving solid black. (Range depends on unit. For points: 0.0 to 8.0; picas: 0p0 to 0p8; inches: 0 to 0.1111; mm: 0 to 2.822; cm: 0 to .2822; ciceros: 0c0 to 0c7.507)
eventListeners	EventListeners	readonly	A collection of event listeners.
events	Events	readonly	A collection of events.
id	number	readonly	The unique ID of the TrapPreset.
imagePlacement	TrapImagePlacementTypes: TrapImagePlacementTypes.CENTER_EDGES TrapImagePlacementTypes.CHOKE TrapImagePlacementTypes.IMAGE_NEUTRAL_DENSITY TrapImagePlacementTypes.IMAGES_OVER_SPREAD	r/w	The trap placement between vector objects and bitmap images.
imagesToImages	bool	r/w	If true, turns on trapping along the boundary of overlapping or abutting bitmap images.
index	number	readonly	The index of the TrapPreset within its containing object.
internalImages	bool	r/w	If true, turns on trapping among colors within individual bitmap images.
isValid	bool	readonly	Returns true if the object specifier resolves to valid objects.
label	string	r/w	A property that can be set to any string.
name	string	r/w	The name of the TrapPreset.
objectsToImages	bool	r/w	If true, ensures that vector objects overlap bitmap images.
oneBitImages	bool	r/w	If true, ensures that one-bit images trap to abutting objects.
parent	Application Document	readonly	The parent of the TrapPreset (a Application or Document).
properties	Object	r/w	A property that allows setting of several properties at the same time.
slidingTrapThreshold	number (range: 0 - 100)	r/w	The difference (as a percentage) between the neutral densities of abutting colors at which the trap is moved from the darker side of a color edge toward the centerline. (Range: 0 to 100)
stepThreshold	number (range: 1 - 100)	r/w	The amount (as a percentage) that components of abutting colors must vary before a trap is created. (Range: 1 to 100)
trapEnd	TrapEndTypes: TrapEndTypes.MITER_TRAP_ENDS TrapEndTypes.OVERLAP_TRAP_ENDS	r/w	The shape to use at the intersection of three-way traps.
trapJoin	EndJoin: EndJoin.MITER_END_JOIN EndJoin.ROUND_END_JOIN EndJoin.BEVEL_END_JOIN	r/w	The join type of the trap preset.
